Earth and nature in the Lemurian epoch
Atmosphere: thick air, very turbulent
Earth surface: soft crust
Animals: only amhibians, birds, lower mammals .. no modern higher mammals
Plants: resembling palms but gigantic sizes
Lecture coverage and references
The air was much thicker even than in later Atlantean times, the water much thinner. And what forms the firm crust of our earth today was not yet as hard as it later became.
The world of plants and animals had developed only as far as the amphibians, the birds, and the lower mammals, and as far as vegetable growths which resemble our palms and similar trees. However, all forms were different from what they are today. What now exists only all in forms was then developed to gigantic sizes. At that time our small ferns were trees and formed mighty forests. The modern higher mammals did not exist.
Turbulent volcanic forces
The place on earth in which this stock of a coming race of men was developed was especially suited for this purpose. It was one where the then still turbulent earth had become fairly calm.
For Lemuria was turbulent. After all, the earth at that time did not yet have its later density. The thin ground was everywhere undermined by volcanic forces which broke forth in smaller or larger streams. Mighty volcanos existed almost everywhere and developed a continuous destructive activity.
Animal life was subject to even greater changeability. We shall speak further about the animal species existing at the time of the development of man and about their origin, as well as about the development of new animal forms after man already existed. Here we shall say only that the existing animal species continually transformed themselves and that new ones were developing. This transformation was of course a gradual one. The reasons for the transformation lay in part in a change of habitat and of the manner of life. The animals had a capacity of extraordinarily rapid adaptation to new conditions. The malleable body changed its organs comparatively rapidly, so that after a more or less brief period the descendants of a particular animal species resembled their ancestors only slightly. The same was the case in even greater measure for the plants. The greatest influence on the transformation of men and animals was exercised by man himself. This was true whether he instinctively brought organisms into such an environment that they assumed certain forms, or whether he achieved this by experiments in breeding.
